If an HP Pavilion DV4270US LCD is not clearly cracked, there are other factors in diagnosing a screen that is not working. There are three parts that go to the LCD image, the LCD data cable, the LCD and the FL Inverter. If you have a HP Pavilion DV4270US with a dim screen, either the LCD cable is bad or it is not getting power to the bulb. If no power is getting to the bulb, it could be that the inverter is bad and not sending 6V of power to the bulb. You need to test the inverter for power output. If power is coming out of the inverter, the bulb inside the LCD is bad and the LCD will need to be replaced.
